Calculated d-spacing values (Å)

For NaCl, an FCC lattice, the comparison is made assuming the d-spacing of the (111) plane, which is the smallest plane, so ($d_{{111}} = \frac{{a}}{{\sqrt{{1^2+1^2+1^2}}}} = \frac{{a}}{{\sqrt{{3}}}} \approx 3.256 Å$), where $a$ is the lattice constant for NaCl.

Comparing with known d-spacing of 5.64 Å

  • Kα Fit: 5.23 ± 0.06 Å (Error: -7.22%)
  • Kβ Fit: 5.22 ± 0.07 Å (Error: -7.45%)
  • Combined Fit: 5.23 ± 0.04 Å (Error: -7.34%)

Calculated d-spacing values (Å)

For LiF, the comparison is made assuming the d-spacing of the (100) plane, so ($d_{{100}} = \frac{{a}}{{\sqrt{{1^2+0^2+0^2}}}} \approx 4.026 Å$), where $a$ is the lattice constant for LiF.

Comparing with known d-spacing of 4.03 Å

  • Kα Fit: 3.5 ± 0.1 Å (Error: -12.08%)
  • Kβ Fit: 3.5 ± 0.1 Å (Error: -13.24%)
  • Combined Fit: 3.52 ± 0.07 Å (Error: -12.67%)
